"Sans..? P..papyrus?" You walked down the snow path as dust clouded the sky. 'Please be ok. Please be ok.' Your soul was slowly changing to a pink soul, the fear soul, as you picked up the pace.

Your soul changed it's color depending on your magic level and your emotions. Fear was your strongest soul, which also made people not mess with you. Your eyes started to glow pink as you noticed two things on the ground.

"N-no," you sprinted to see Sans's jacket and Papyrus's scarf, "NO NO NO NO! NO PLEASE!" You gripped the scarf and jacket as pink and black tears fell into the snow. Your body was starting to get an outline of dark pink as your left eye glowed pink and your right eye glowed black.

"I. Will kill. That. DEMON." You growled as you put the blue jacket over your (f/c) shirt and the red scarf around your neck. You teleported to the Judgement hall and waited. You leaned against a pillar before you sighed. "If only Sans were here... he'd know how to fight a human..." You said in defeat. You were only about 14, how could you fight a human?

"💧❄✌✡ 👎☜❄☜☼💣✋☠☜👎"

You perked up at the voice. "D..dad?" You called out, your soul was slowly fading back to it's original white self, hoping to hear your father again.

"💧✌☠💧 ✌☠👎 🏱✌🏱✡☼🕆💧 ✌☼☜ 🕈✋❄☟ ✡⚐🕆📬 💧⚐ ✌💣 ✋📬 ✡⚐🕆 🕈✋☹☹ 👎☜☞☜✌❄ ❄☟✋💧 ☟🕆💣✌☠📬"

You started to smile as tears rolled down your cheekbones. You then saw three ghosts, your brothers and father. Papyrus had a cut along his neck, Sans had a cut along his chest, and Gaster looked googy.

"YOU CAN DO IT!"

"*give this kid a bad time."

"❄☟☜✡ 👍✌☠☠⚐❄ ☼☜💧☜❄ ☞⚐☼☜✞☜☼📬"

You nodded as your heard footsteps. Your soul snapped into it's fear form. Your eyes started to glow hot pink as you saw the demon who fell into the undergrounds. "Lets 'cut' to the 'point' here. You are a dirty brother killer and you're gonna pay." You growled, Frisk got ready to only be killed in a second.

You kept killing Frisk in different patterns, sometimes like Sans, sometimes like Papyrus, and you finished them off the way Gaster taught you. Your soul was mixing with the colors of black and hot pink.
